What if science class felt less like studying out of a textbook and more like an unforgettable field trip? From viral glitter-bomb traps to backyard engineering marvels, former-NASA-engineer-turned-YouTuber Mark Rober has spent years proving that curiosity is contagious — and that the best way to teach science is to make it impossibly fun. In conversation with TED’s Whitney Pennington Rodgers, Rober shares how play, wonder and a healthy dose of mischief can transform the way kids learn … and gives a peek inside his plan to bring magic to every classroom in America. (This conversation was part of an exclusive TED Membership event. TED Membership is the best way to support and engage with the big ideas you love from TED. To learn more, visit ted.com/membership.)

Humans aren’t just social — we’re ultrasocial, wired like bees and ants for deep connection. So what happens when smartphones take over childhood, tablets replace textbooks and AI companies infiltrate our kids’ lives? Social psychologist Jonathan Haidt lays out three principles of technoskepticism — and explains why, two years after sounding the alarm in “The Anxious Generation,” he’s more concerned (and hopeful) than ever before.

Philosopher Meghan Sullivan and space architect Ariel Ekblaw don’t usually work at the same altitude … but put them in a room together, and they’ll answer the big questions. Drawing on wisdom from Aristotle to astronauts, they discuss what humans inherently owe each other, what it takes to live a good life and what a rulebook for a better world might look like.
